Abstract

The use of PHASE CHANGE MATERIAL to enhance the capacity of energy storage/ release is the subject ofmany new researches on the management of energy supply. Study of these systems is directly related tothe SOLID-LIQUID PHASE-CHANGE problem, in which the evaluation of temperature distribution, position ofphase-change front and liquid or solid fraction becomes a basic problem. Study of freezing and meltingprocess with regard to NATURAL CONVECTION in the liquid phase is the main purpose of the present paper.For this purpose, a rectangular finned container of PHASE CHANGE MATERIAL is intended. Fins are used toenhance the heat transfer rate. This fact necessitates the use of immersed boundary condition on thesolid phase. Hence, the melting process considering both the effects of NATURAL CONVECTION andmovement of solid phase is studied. The freezing process is also studied taking into account the naturalconvection with no need to impose the immersed boundary condition. LATTICE BOLTZMANN METHOD isused as a numerical method and results are reported based on the dimensionless parameters. Based onthe results, the effects of NATURAL CONVECTION are negligible during freezing process, while imposing theeffects of NATURAL CONVECTION provides a significant change in the required time for complete melting ofthe PHASE CHANGE MATERIAL.
